IV. Approval of Minutes -- November 2. 2020
Chairman Benton asked if everyone had a chance to review the Minutes as presented.
All indicated they had. Hearing no changes/corrections, Mr. Benton called for a motion.
A motion approving the November 2, 2020 Minutes as presented was made by Mr. Griffin,
seconded by Mr. Carrano, and approved unanimously via voice vote.
V. Announcements -- None
VI. Public Input
Mr. Benton called on anyone from the public who wished to speak.
Russell Hermann, 566 Redwood Court, Sebastian. He identified himself as the Vice
President of the Friends of St. Sebastian River. He stated that members of the Friends
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 2
MINUTES OF DECEMBER 21, 2020
of St. Sebastian River have been going to residents whose properties abut the canals
and getting their input about what they see and what recommendations they have for this
Sub -Committee. He commended the Sub -Committee for their work, as what they are
doing is extremely important. He further stated that the residents are not very aware of
what has happened and what is happening. He suggested it is important that the
residents be brought up to speed about what has been done and what the City's
expectations are. He hopes that the information can be put on the City's webpage or by
some other means of getting the information out. He is disappointed that there are so
few people from the public attending these meetings. He is aware it is an important and
difficult task, but he asks if there is some method of letting the people know about the
meetings. The Fdends of St. Sebastian River are doing their best to explain to people
why it is important that they come to these meetings in order that they be educated about
what is happening. Transparency is not a negative but is a positive action permitting the
City to explain to the residents all the positive actions it is taking to improve the City.
Bob Stephen, 150 Concha Drive, Sebastian. He thanked the members of the Sub -
Committee for their work. He is disappointed that City Council decided to spray the
pesticides immediately. He repeated a list of chemicals that are permitted to be used in
the pesticides. He voiced concern over the potential health hazards of them. He stated
that last week spraying was done. He stated that, if the City has to use the chemicals in
and around the canals, it should post public notice before spraying is done. He asked
why the City does not do that and asked that the City perform due diligence in regard to
this matter.
There being no one else from the public in chambers or on Zoom who wished to speak,
Mr. Benton moved to the next agenda item.
VII. New Business
A. Non -chemical controls table
Review listed methods and associated information for inclusion into
the IPM Plan
ii. Discuss methods currently being utilized by the Stormwater
Department and contractors
Ms. Haigler made a PowerPoint presentation reviewing the non -chemical pest control
methods that were discussed and some others that had come up (SEE ATTACHED).
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 3
MINUTES OF DECEMBER 21, 2020
She explained that most of these agents are already in practice within the City. She asked
for comments/cluestions from the Sub -Committee members.
Mr. Carrano:
Even though bivalves were mentioned, most of the waterways within the City do
not have these. Ms. Haigler stated there are actually shellfish in the canals. Mr.
Carrano stated there are freshwater clams and freshwater mussels, but usually
those are found at a very low concentration. So their use in bioremediation is
almost nothing. Ms. Haigler stated that is true. She put them on the list because
they are a species that can help and, if there is a way to enhance them, that would
be helpful. She is not sure if there is a way, but she put it on the chart for
consideration. Along the shoreline of the Stormwater Park the bivalves can be
seen because the wading birds search for them.
Dr. Cox:
Asked how long the Sub -Committee members have to comment on the list that
Ms. Haigler sent out. Ms. Haigler stated she was hoping to get the list approved
at this meeting. That does not mean that this list is limited to what is already on it;
it is just so that the list be approved today, and then more items can be added as
they are discovered. That information can be emailed to her. The whole Plan is
not finalized, but she wants to section some things off and move forward. The
Plan document is always open for comment until final approval.
One of his pet peeves is that he goes around the City and watches the landscaping
contractors do their lawn work. They do not collect the grass clippings, they just
scatter them. When the rain comes, they wash into the ditches and into the canals.
He thought there was something in the City's fertilizer ordinance that says that all
of the grass clippings are to be bagged. So this is contributing into whatever Is
getting into the lagoon. He asked if there is something in the City's fertilizer
ordinance to that effect. Ms. Haigler stated she does not believe so. Mr. Griffin
does not believe that is in the ordinance, and it is for all intents and purposes
impractical. However, what the stormwater crew does is once a year from the
major ditches and canals they try to physically remove all the cut vegetation, and
that is a huge undertaking. Most years, they do a very good job of it. This year
has been exceptionally difficult, but they still endeavor to do that for the rest of this
fiscal year.
When it comes to the $20+ million in grant dollars that is available, he knows of
several folks who are skilled at lobbying, and if there is some place staff thinks they
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 4
MINUTES OF DECEMBER 21, 2020
should go with a map, knock on doors, or send emails, they would be happy to do
that. Mr. Griffin stated the City has allocated the matching funds. The agency that
decides the current grant applied for, the Florida Department of Economic
Opportunity, is right now without an agency head, so that makes it especially
difficult. However, as part of the bigger question in terms of being successful on
this grant application and many other grant applications which the City is going to
need to really get the system the way it should be, is to complete the
Comprehensive Stormwater Master Plan, with all its facets well integrated. One
of the principal criteria the City insisted on is that the firm have a demonstrated
track record of having secured $50 million to $100 million in recent years in federal
grant dollars. The firm that has been selected has done that, and the City believes
they have significant expertise to be able to help the City secure the very
substantial amount of money —way more than $24 million —that is going to be
needed to do all that is needed to put the stormwater system in the shape that it
needs to be in. Staff has been trying to work around there being no head of the
FDEO by working with the governor's office. To date, they have not been
successful. Dr. Cox stated the City only has to say the word, and his group will do
lobbying to go after those funds.
Ms. Callaghan:
Regarding biological, cultural, and mechanical controls, which are what are being
discussed presently, she has a comment on the column entitled 'Description" and
the column entitled "How to Implement." She suggested, especially on the "How
to Implement' column, regarding the second line on the blue tilapia where it says:
"Since the entire stormwater system is interconnected with multiple outfalls into
environmentally sensitive waters..." she feels it should be described more in depth
as to how that can be implemented. She feels that the language there presently
(a) is an opinion, and (b) maybe there is something in a column she did not see.
She suggested that maybe the column header needs to change or regarding a
description, she suggested there be more detail as to where the Sub -Committee
is in the process. Ms. Haigler stated this is a general table, and there are different
ways of approaching each plant. Regarding exactly what would be done and
where it would be done, the Plan is not at that stage yet. The statement about the
fish is not an opinion, but the entire stormwater system is interconnected with
multiple ouffalls into environmentally sensitive waters. That disqualifies the
stormwater system from adding carp or tilapia. That wording was cut off on the
document, and she will correct that. Mr. Carrano stated that it is important to note
that both of those fish would have required permits in order to be put in, and they
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 5
MINUTES OF DECEMBER 21, 2020
could be changed so the fish cannot escape, but that is just an extra step. Ms.
Callaghan stated that is the level of detail that she is looking for to be added to the
statement. Mr. Benton stated staff will make that adjustment and staff will expand
the columns in the future to include all the verbiage. Mr. Benton opined that there
are tilapia already in there. Ms. Haigler stated there are some naturally occurring
ones, different ones. They are not the blue.
Hearing no additional comments/questions from the Sub -Committee members, Mr.
Benton called for public input on New Business, Item A.
Bob Stephen, 150 Concha Drive. He stated that after reading some of the information,
he has not seen anyone dredging the City's canals. He has not seen any manual weed
pulling. He stated the City has said that it will bankrupt the City to have manual weed
pulling. He asked if the City has applied for grants to help with this. He suggested there
is a lot of money to be had by way of grants. He thinks the feds are extremely excited
about cleaning the up the lagoon. He does not understand why the City is not getting
money that way.
Ms. Haigler addressed the subject of dredging and the manual removal. Manual removal
occurs regularly, especially around the dams and weirs. That does not mean that it is
widespread; it means that the City does practice it. Perhaps it could be enhanced in the
future. The dredging is occurring every day. It may not be in everyone's back yard, but
that is basically what the stormwater team has been working on for the past months
consistently. She stated they have taken a lot of truckloads of muck and vegetation out.
She stated Mr. Griffin could speak to that.
Mr. Griffin stated that most of the City's stormwater system is only intermittently wet. In
those portions that are intermittently wet and hence intermittently dry, the principal
method of control is mechanical removal. So they are mowing, they are using hydraulic
excavators and other heavy equipment and constantly removing vegetation, debris,
muck, slough material, reshaping and reconfiguring the swales, ditches, and canals. It is
only the portion of the City's system that is wet all the time which his department looks at,
as they are doing now, using the herbicides. The City does not use herbicides on any of
the intermittently wet/intermittently dry areas in the stormwater system. Some mechanical
removal and harvesting and dredging are the principal methods of control of vegetation
in most of the City's stormwater system.
Mr. Carrano suggested care be taken when the term "dredging" is used versus
"excavating." He stated those two terms should not be equivalent, although they might
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 6
MINUTES OF DECEMBER 21. 2020
be very similar. Mr. Griffin stated that is correct, and the City is interested in doing true
dredging in the canal system and has applied for a major grant to do that, a $24 million
grant to reconstruct, reconfigure, and dredge the canal system and establish a littoral
zone of native vegetation that is self -maintaining in the City's canal system. He is hopeful
that the City will receive the grant. The City has set aside its match already to show its
commitment to pursuing that grant.
This being an action item, Mr. Benton called for a motion approving the non -chemical
controls table, adding the items that were discussed above. A motion was made by Dr.
Cox to tentatively approve the non -chemical controls table, with additions as discussed
and set forth above, seconded by Mr. Carrano and approved unanimously via voice vote.
B. Introduction to chemicals used in aquatic plant management
EPA -approved pesticides
Ms. Haigler made a PowerPoint presentation on aquatic herbicides (SEE ATTACHED).
She stated the State only approves certain active ingredients, of which there are 17. The
active ingredients may be formulated and sold under different trade names, of which there
are more than 100 different trade names currently used in Florida. They all fall under one
of these active ingredients. She reviewed the various environmental and chemical
variables to applying these products. It is up to the licensed applicator to follow the
herbicide label use exactly. It is important to remember that there are labels on these
chemicals, there is a set of safety data sheets, and these labels are the law. Also
reviewed were the sheets which contain specific technical information which is useful in
the event of a spill or accident. The different mixes of chemicals are changed during
different seasons. That is all part of the process to keep them from developing a
resistance. She asked if there were any questions or comments on this section.
Dr. Cox:
Stated that one problem that is present when there is a long list of chemicals is
that it tells you that there is minimum harts to certain species with the proper use
of that particular chemical. He stated that when several chemicals are blended, it
is not known what the effects are going to be because these chemicals in
combination are not tested. Ms. Haigler stated that the combinations listed are
recommended in common practice. She does not have the research on that, but
she stated it can be researched and can be discussed when the Sub -Committee
goes further into the chemicals. Dr. Cox asked Ms. Callaghan if she knows if there
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 7
MINUTES OF DECEMBER 21, 2020
is any kind of study done on chemicals mixed together like this. Ms. Callaghan
stated she is not able to provide that information today. She would have to do
some research on that. Mr. Griffin stated that he has attended multiple
presentations of papers on ongoing research in which a combination of
methodologies and a combination of chemicals are used. The results are reported
in great detail. There are many examples in which research is conducted
specifically on different mixes of chemicals in scientific papers that are refereed,
published, and well versed.
Hearing no further comments/questions from the Sub -Committee members, Mr. Benton
opened the meeting to public input on Item B, Section I, EPA -approved pesticides.
Bob Stephen, 155 Concha Drive. He asked about the City's permit for spraying. He
also asked about the condition of the waterways with use of these chemicals. He
addressed the report card that came out recently which states the nutrient level is very
high in the lagoon because of adding nutrient levels in the St. Sebastian River which goes
out to the Lagoon.
Seeing no one else in chambers and hearing no one on Zoom who wished to speak, Mr.
Benton moved to the next item.
ii. Chemical adjuvants
Ms. Haigler reviewed the next part of the PowerPoint presentation (SEE ATTACHED).
She explained that adjuvants are the chemicals that are added to the herbicides for
different reasons. She intends to list the adjuvants in the chemical table and include them
with their environmental impact quotient the same as is done with any of the chemicals.
She described the different categories of the adjuvants and surfactants. She stated that
at the next meeting she will have a scale of what percentage of adjuvants is used
compared to the percentage of chemicals. It also needs to be studied as to what the
consequences may be of those chemicals themselves. That will be addressed on the
sheet along with the chemicals. She stated that the PowerPoints that are being presented
at this meeting will be available on the Stormwater IPM website this week. Dr. Cox asked
how to get directly to the Stormwater IPM website. Ms. Haigler stated there is a direct
link from the Natural Resources Board website.
Mr. Benton asked for questions/comments from the Sub -Committee members. Hearing
none, he opened the meeting for public Input regarding Item B, Section ii, Chemical
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 8
MINUTES OF DECEMBER 21, 2020
Adjuvants. Seeing no one in Chambers and hearing no one on Zoom, he moved to the
next item of the agenda.
Vill. Old Business
A. Review the "Introduction" Section of the Stormwater IPM Plan
Discussion of changes and vote to approve
Mr. Benton reviewed that this section of the Plan was presented two meetings ago. After
some discussion, Ms. Haigler had made some revisions. It is open to the Sub -Committee
members for discussion now, and hopefully a vote to approve this section can be done.
Ms. Haigler reviewed the introduction which was attached to the meeting agenda, stating
that everything in yellow (SEE ATTACHED) is what she changed before the November 8
meeting when it was discussed. This is basically the introduction to the program itself
which will be implemented much the same as the IPM Plan for the parks. Anything
different from the parks IPM Plan is highlighted in yellow. Everything in turquoise has
been added since the last discussion. She called for questions/comments from the Sub -
Committee members. Hearing none, Mr. Benton called on anyone from the public who
wished to speak on this item. Seeing no one in Chambers and hearing no one on Zoom,
Mr. Benton called on any further comments/questions from the Sub -Committee members.
Dr. Cox stated it looked to be very straightforward.
Mr. Benton then called for a motion. A motion by Dr. Cox for tentative approval of the
proposed Introduction to the Stormwater IPM Plan was made, seconded by Mr. Carrano,
and approved unanimously via voice vote.
IX. Sub -Committee Member Matters
Dr. Cox reviewed that at the council meeting on December gth, the Mayor suggested that
the City hold off for a month on approving the contract with Aquatic Vegetation Controls
to discuss further what happens when the vegetation in the canal is sprayed, no matter
what it is and no matter what is sprayed, to look at the effects of that spraying because it
causes a lot of dead matter that sinks to the bottom and becomes part of the muck
problem. It was decided not to approve that hold, so the issue still remains. Dr. Cox
stated when the airboat came through, he sprayed all down the one side across from the
Stormwater Park and then came back down on the other side. Where he sprayed is now
just a brown, yucky mess, which is now going to become part of the muck. Dr. Cox
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 9
MINUTES OF DECEMBER 21, 2020
stated he and the employee who was doing the spraying had a discussion about what
was being sprayed and the rationale for what was being sprayed. Dr. Cox suggested that
it would be useful for the company doing this work, if they are willing, to come and talk to
the Sub -Committee and explain how they go about doing it and what goals they have.
Dr. Cox stated that the thinking has been, if the invasive species are killed, the native
species will regrow. Dr. Cox stated they will not. He has had conversations with three
biologists, and they have all said, unless you are prepared to go back in and replant the
native species, they will be gone completely every time because of the invasive material
that is there. So all that is being done is spraying without any useful effect except to keep
the invasives from spreading all across the whole surface of the canal. When Dr. Cox
suggested doing it by other means, the employee said no, it takes too long and is too
expensive to do it by hand, and they do not have any equipment that will come in there
and pull it out. Dr. Cox would like to hear from Aquatic Vegetation Control (AVC)
regarding their experiences and how that cycle can be broken. He asked Mr. Griffin if it
would be possible to have AVC come and give a presentation on these matters.
Mr. Griffin suggested that the Sub -Committee come up with an assignment to themselves
to do that research. He further stated that the employee answered that question when
talking with Dr. Cox and saying there is really nothing else that can be done that is cost
feasible. Dr. Cox stated the employee in the airboat suggested that we should invite the
scientist who works for the company to come and discuss the rationale for what they are
doing. Mr. Griffin stated he will write to the principal of the company and will evaluate
their answer and will report back to this Sub -Committee.
Mr. Carrano stated he thinks the problem is twofold, and the first part of the problem is
that the nutrient input into all the stormwater drains, creeks, and canals is excessively
high. The advantage is going to go to whichever plant grows the fastest. So the non-
native vegetation is going to outcompete constantly the native vegetation. The second
part is that, by using chemicals and allowing this material to die and sink to the bottom, a
habitat is created that is not suitable for the native vegetation to take hold. He pointed
out that what was found in the past is the organic matter is a seed bed for the vegetation
that was just killed. While some of these chemicals may work on the vegetative stalks,
they may not work on the dormant seeds that, when the vegetation decays, are in that
organic mess that is there, and as soon as the chemical influence goes away, they sprout
and take hold. That is why it is very difficult to kill this material and remove it. If it is not
removed from the waterway, the problem is never going to be solved. Mr. Griffin stated
there can be equal problems with mechanical removal also, where the growth rates are
many times more after mechanical removal than they were before. He suggested that
part of the answer to this question is when spraying is done and how often spraying is
done. What was put in place this year is probably the worst thing that could possibly have
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 10
MINUTES OF DECEMBER 21, 2020
been done --let the vegetation take off, grow exponentially, and then come in after waiting
12 months and try to control it. Timing is everything in terms of staying in front of the
situation, so you do not wind up with that large amount of mass that has to be killed. Mr.
Carrano suggested another question that should be asked is, should you spray. Because
spraying is not the answer all the time. Spray when it is needed, but there may be some
times when spraying should not be done. Just because people do not like the look of the
vegetation in the waterways does not mean it has to be killed.
Ms. Haigler stated this Sub -Committee plans to do what was done with the parks IPM
Plan. The stonmwater assets will be divided into classes, i.e., the canals, ditches, and
structures, and each of them will have a section where it will be discussed as to where
that level is. Mr. Griffin stated that is a good point. With the City's stormwater system,
which is quite extensive, most of the system is intermittently dry or intermittently wet, and
none of that system is sprayed ever. So that is the right treatment, and that is done solely
mechanically. It is only the wetted portions of the system that are wet all the time that
need some judicious herbicide application. Mr. Carrano added that in those sections the
most important areas are the pinch points such as the dams and weirs which have to be
maintained by some mechanism. Ms. Haigler stated staff has records of where spraying
was done in the past, and those are the same places the problems still exist. She added
that what this IPM Plan is designed to do is establish a maintenance program that is going
to guide the processes going forward. Since there was nothing done for a year, that has
led to the vegetation getting out of control. That is why there is a chemical applicator
trying to get it under control.
Dr. Cox suggested that ideally, someone could come along behind the airboat and scoop
up all the mess that is now present along the canal. Mr. Griffin explained that is exactly
what the Stormwater Department has done. Spraying has been done with the thought in
mind of what would be the impacts immediately afterwards. The amount of spraying was
substantially limited so that there would not be any secondary impacts. That is part of the
difficult job of catching up after doing nothing for 12 months. He opined that his
department will soon be back in the maintenance mode so that there is not that threat of
doing damage in the process of control. An attempt is being made to strongly limit the
amount of chemicals that are used. Regarding mechanical control, Mr. Griffin stated that
as much money was spent for one removal of 1,800 feet of aquatic vegetation from the
Hardee Park canal area as was spent for the herbicide application for the entire
stonmwater system for the entire year. Then, unfortunately, within a month after the
mechanical removal, it came back to the same situation that it was prior.
Dr. Cox related that one question that was posed to him was that, why do we want to get
rid of it anyway. Natural vegetation is not going to come back because no one is quite
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 11
MINUTES OF DECEMBER 21, 2020
sure what the natural vegetation condition was there before. Unless it is choking the
canal or doing things that prevent the flow, then leave it alone. Mr. Griffin agreed, but the
canal system is the most important portion of the stormwater system. It is necessary to
move the water through the City, or else there will be terrible flooding. So the stormwater
capabilities of the canal system are attempting to be maintained, and the City is trying to
do it through control of the invasives. It is well known what the invasives are. Those are
the only ones that are being targeted. He is hopeful that after this initial effort the canal
system will be back in the maintenance mode. The amount of chemicals that was used
in prior years was a very small quantity and a very small dollar amount.
Ms. Haigler stated it is important to remember that with the City's canal system, there is
a series of dams and weirs and structures where there are major pipes that go underneath
those structures that are not visible. Because of that, only about half of the canal system
is accessible by the kind of equipment that would be required for mechanical removal or
even for harvesting of sprayed vegetation. So that is something to be kept in mind.
X. Staff Matters
Ms. Haigler stated the kickoff meeting for the new landscape maintenance contract for
the CRA area was held. As part of the kickoff, there was a copy of the Parks IPM Plan
presented, and discussion was held on each of the items that the contractor would need
to do to comply with the Plan. The "contractor agreement" was signed, and the contractor
is using the City's signage and the City's forms. She expects great results from our new
partnership with Tropical Landscaping. Mr. Benton agreed.
Mr. Griffin stated he will follow up on what Dr. Cox requested him to do, and he will report
back on what can be done to allow "good" non-invasive vegetation to survive.
Mr. Benton wished everyone a Merry Christmas and Happy New Year
XI. Items for next Aoenda
A. Further chemicals discussion
Ms. Haigler stated there will be further discussion of the chemicals. She will have the
prior Applied Aquatics treatment sheets to refer to in the discussion. There will be a
preliminary chemical spreadsheet to review.
Mr. Benton stated that for the next meeting the invoice and data sheets from the first
month from the current contractor should be available. He stated the date for the next
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 12
MINUTES OF DECEMBER 21, 2020
meeting is January 11, 2021.
XII. Adiournment
There being no further business, Mr. Benton adjourned the meeting at 3:15 p.m.

OUR HISTORY
• Nick Szabo Founder, grew up on a hog farm in
Ontario, Canada where his love for Agriculture
began.
• In 1992, his Journey began in the fertilizer
business where he set a precedent through the
design of his equipment which resulted in 300%
increased industry efficiency.
• In 2008, Nicholas ventured over the border and
began working with North America's Largest farms
converting what most saw as a waste and selling
over $1 million worth of fertilizer in the form of
manure to local crop farmers. Bridging neighbors-
and big farms together by applying millions of

AQUATIC WEED MANAGEMENT TODAY
• Current management of Algae/
Hydrilla/Water Hyacinths consists
of the use of toxic, harmful
chemicals, further degrading fresh
water bodies and leading to
increased Algae blooms due to the
massive amounts of nutrients these
plants release into the water as
they die and sink to the bottom.
AGUA CULTURE - OUR SOLUTION
• To harvest unconsolidated sludge/muck
and algae/aquatic weeds, "the product"
via our patented system.
• Immediately process the product into a
liquid form.
• Pump the product to shore via our
patented hose.
• Apply the harvested liquified product as
a soil amendment for nutrient uptake via
growing native grass. This grass can
eventually be harvested to further
remove phosphorus from the area and
sold as hay.

INTEGRATED PEST MANAGEMENT PLAN
I. INTRODUCTION
Scope
The City of Sebastian's stormwater conveyance system encompasses 9 miles of canals, 80
miles of ditches, and over 15 ponds and retention areas. Other stormwater assets include: 310
culvert pipes and catch basins, 7 baffle boxes, as well as countless swales, road crossing pipes,
dams, weirs, right-of-ways and a seawall perimeter. The Stormwater and Public Works
Departments are charged with maintaining all of these features so that the treatment,
transportation, and storage capacity of the entire conveyance system is preserved, while also
ensuring the safety of City staff, residents, structures, wildlife, and the surrounding natural
waters.
The City of Sebastian is bordered on the east by the Indian River Lagoon (IRL) and on the west
by the San Sebastian River (SSR). Both of these waterways are environmentally sensitive,
support a large number of native species, and are integral to the natural health of our region.
Therefore, the City must also serve as a steward to the IRL and SSR by ensuring that the
stormwater entering these waterways is as healthy as possible.
In order to best manage pests within the stormwater system, while also protecting
environmental health, City staff and contractors will continue utilizing the principles of
Integrated Pest Management (IPM) through the implementation of this IPM Plan. Please note
that this plan will not apply to any stormwater features located within any planned unit
development (PUD), as these subdivisions have direct contracts with the water management
district to design and maintain their own stormwater system. Also not covered by this plan is
the City's cemetery, parks, or other properties, as these features are managed collectively by
the City's Leisure Services Department and are addressed in a separate "Parks and Properties
IPM Plan," which was adopted by City Council on October 14'", 2020.

INTEGRATED PEST MANAGEMENT PLAN
IPM Sub -Committee
In October of 2020, the Stormwater IPM Sub -Committee was formed to assist City staff in the
development of an Integrated Pest Management Plan for the City of Sebastian's stormwater
conveyance system. The sub -committee is to be comprised of the Stormwater Director, IPM
Coordinator, three Natural Resource Board Members, and two local scientific consultants.
The role of the IPM Sub -Committee is to assist in the development of a cohesive IPM Plan,
advise on pest management issues, and evaluate the City's progress towards the goals of the
IPM Plan. The Sub -Committee will review and approve the annual IPM report before it is
presented to City Council. As part of the annual review, Sub -Committee Members will
evaluate the current techniques and products to ensure they are based on the best available
technologies and scientific information available. Recommendations will be made regarding
changes to the annual reporting process and the IPM Plan document.
In the development of the initial Stormwater IPM Plan, the IPM Sub -Committee will meet bi-
monthly. Following adoption of the final IPM Plan by City Council, the committee will meet
annually, unless more frequent meetings are needed, as determined by staff. All IPM Sub -
Committee meetings will be held in compliance with Florida's Sunshine Laws, with public
notice, posted agenda, and minutes taken by a recording secretary.
IPM Coordinator
In order to provide for the planning and oversight of the IPM program, the position of IPM
Coordinator is established. The appointed IPM Coordinator shall be a member of City staff
who is in a position related to environmental or planning, who shall coordinate with the
Stormwater Director. Together, they will lead the creation and implementation of the IPM Plan,
which will apply to the City's pest management activities on all of its stormwater ponds,
canals, and ditches. Their responsibilities will also include the following:
• Serve as liaison to IPM Sub -Committee
■ Monitor that City staff are adhering to the IPM Plan Standard Operating Procedures
■ Maintenance of accurate records on IPM implementation and use
■ Keep records of staff training in Green Business Best Management Practices and staff
pesticide applicator certification
■ Assure the inclusion of City IPM policies and practices in any applicable third party
contracts or purchase orders for pest management
■ Implement outreach efforts and maintain City's IPM Website.
The IPM Coordinator will prepare an annual report of the City's IPM activities, which will be
reviewed each March, by the IPM Sub -Committee and Stormwater Director in an effort to
assess the effectiveness of pest control methods, feasibility of new methods and technologies,
and decide whether revision of the IPM Plan is required.

INTEGRATED PEST MANAGEMENT PLAN
IPM Plan
A pest, by definition is any plant, animal, or pathogen which causes disease, inflicts damage,
or out -competes a more desirable species for an area. In addition, a pest may be
aesthetically undesired, or threaten to impact human/animal health. However, for the
purposes of this plan, noxious aquatic vegetation is the only pest of concern.
According to the 2011 Florida Aquatic Plant Management Act, the uncontrolled growth of this
vegetation poses a variety of environmental, health, safety, and economic problems
(Appendix B).This legislation charges the Florida Fish and Wildlife Conservation Commission
(FWC) with the supervision and control of aquatic plant management. Therefore, the FWC
establishes that a "noxious aquatic plant", is any part or whole of an aquatic plant which has
the potential to hinder the growth of beneficial plants, to interfere with irrigation or navigation,
or to adversely affect the public welfare or the natural resources of the state.
The Florida Aquatic Plant Management Act recommends that the management of these
aquatic plants be carried out primarily through "maintenance programs," as they achieve
more effective management at a lower overall cost.
The City adopts this IPM Plan as its aquatic vegetation maintenance program and adopts the
following definition of Integrated Pest Management as established by the City's IPM Sub -
Committee:
"To promote the most sustainable pest management methods, based on
planning and prevention; which aim to minimize risks to human and
environmental health through the limited use of chemicals, while also remaining
economically feasible."
Goals
■ Protect environmental resources by reducing the amount of pollutants entering surface
and ground water and minimizing effects on native plants, animals and habitats
■ Ensure effective, economic pest management within the City's stormwater
conveyance system, while minimizing health risks to the public, City staff, and the
environment
■ Promote the transparency of the City's pest management activities
■ Increase public awareness of IPM methods and benefits
IPM Program
IPM Policy. The Stormwater IPM plan, as well as future modifications or amendments will be
reviewed and voted on initially and annually by the IPM Sub -Committee, Natural Resources
Board, Planning & Zoning Commission, and then presented to City Council for final approval.
The plan will then be incorporated as City policy through the adoption of Resolution R-21-XX
by City Council (Appendix A).
CITY OF SEBASTIAN PAGE 4
INTEGRATED PEST MANAGEMENT PLAN
IPM Program Coordination. The Stormwater Director and the IPM Coordinator are responsible
for coordinating, tracking, and reporting the implementation of the City's IPM Program.
Tracking Pesticide Use. City Staff and Contractors conducting pest management activities
within the City's stormwater conveyance system are required to record thorough field data.
Accurate records will be maintained on pesticide use and non -chemical methods utilized that
are accessible for reference. All records will be retained for 1 year and stored on the City's
Laser fiche system per record retention schedule.
Staff Training. All City employees who, within the scope of their duties, apply or use pesticides
will be trained on the City's IPM Policies as well as proper chemical storage and use of
personal protective equipment (PPE). A certification course on Green Business Best
Management Practices will be provided through partnership with the University of Florida
Indian River County Extension Office as needed. The training sessions are coordinated by the
Human Resources Director, who will track employees' attendance and ensure that City field
staff holds an active certification.
Licensed Applicators. At all times a minimum of 1 member of City staff must be a state
certified aquatic pesticide applicator. The Human Resources Director and IPM Coordinator will
keep a copy of all staff certifications on file. All pesticide applications will be in compliance
with state regulations regarding applicator licensing.
Information Resources for Staff. The IPM coordinator will act as a resource for City staff to help
identify new pests and pest related concerns, and to assist in determining the best course of
action consistent with the established IPM SOPs. The IPM Coordinator will also seek out and
provide access to expert resources when needed.
Public Outreach. Education and outreach efforts will include distribution of information, either
created internally, or obtained through partnership with local and state government agencies.
The IPM Coordinator will coordinate and keep records of the following:
• A City webpage where the public may obtain information on IPM practices for their
property, view the City's IPM Plan, annual IPM reports, IPM Sub -Committee minutes,
and pest management treatment records.
• The City's efforts to promote the reduction of urban pesticide use through social
media, the City's website, print and television media.
• The City's outreach to pest control operators (PCO's) and landscapers.
• Distribution of IPM information and resources at public outreach and community
events.
• IPM information distributed to residents through the "New Homeowner Folders" during
the final planning and zoning inspection.
• Updates and status reports following the annual report and as requested by City
officials.

INTEGRATED PEST MANAGEMENT PLAN
Contract Provisions. The Procurement Coordinator will review contract provisions and/or
amendment(s) to agreements that provide pest management services within city maintained
ponds, canals and ditches covered under this IPM Plan. All such contractors shall be required
to review and sign the "contractor agreement" (Appendix B). Contract work will be
monitored to ensure that City IPM policies and practices are adhered to by all contractors
performing pest management work.
Regulatory Reporting. The IPM Coordinator will handle reporting to regulatory agencies, which
credit the adoption of an IPM Plan as a Best Management Practice (BMP).
• Incorporate the IPM Plan into the Florida Department of Environmental Protections
(FDEP)'s National Pollutant Discharge and Elimination System (NPDES) Phase II, MS4
Permit Cycle 4, Year 2 Annual Report (September, 2022) and the Cycle 5 NOI
(September, 2024) as a new BMP for Element 6: Pollution Prevention/ Good
Housekeeping.
• Add as new project and update through the statewide Basin Management Action Plan
(BMAP) annual report on water quality projects.
• Add as new activity and provide update to the Indian River Lagoon Council for the
Indian River Lagoon Comprehensive Conservation and Management Plan (CCMP)
annual report on lagoon -related accomplishments.
Community IPM Cycle
This established cycle (Figure 2) will serve as the guideline for IPM Plan development and is
based on planning and prevention, with the use of chemicals as the last resort for pest control.
1. Inspection and Monitoring: Staff routinely scouts the waters and surrounding landscapes
to locate pests. Pest populations are monitored by visual checks and traps.
2. Identification: Pests must be accurately identified. Life history attributes are to be known
for each pest identified. This step is key to effective treatment.
3. Planning: The focus is on prevention- what it takes to keep pests out. Determine what
action is needed and whether a threshold has been crossed. Proper techniques and
timing are for required management.
4. Implement Strategy: All pest management strategies are classified as biological,
cultural, mechanical, or chemical. All methods are combined to maintain pests at
acceptable thresholds.
• Bioloaical Control: enhances natural enemy populations by creating
habitat or adding populations
• Cultural Control: Disrupts the pest's environment by removing pest attractants
or utilizing pest resistant variety of desired species
• Mechanical: Creates physical barrier to pest entry
• Chemical Control: the last tool in the IPM toolbox, the goal is evaluate costs
and benefits to choose the least -toxic and most feasible option available
that will do the job
CITY OF SEBASTIAN PAGE 6
INTEGRATED PEST MANAGEMENT PLAN
5. Record Keeping: Accurate record keeping is essential to a successful IPM program. Data
must be kept on control methods implemented, chemical usage by staff, and purchase
orders. Determine if control methods were effective by knowing what has changed
through trap counts and observation.
6. Evaluate Effectiveness: Document if the program is meeting expectations. Establish if all
actions have been in compliance with the City's IPM Standard Operating Procedures
(SOPs). Assess what was learned and determine whether the plan needs revised.

Standard Operating Procedures
When selecting and implementing a pest management strategy, from this plan, the following
will be considered by Citv Staff:
Site Factors. Use and function of the waters and surrounding landscape.
• Considering the use and function of the assets and the surrounding landscape,
stormwater features are divided into four functional categories (Figure 3) in which the
action threshold and methods are determined:
➢ Structures: including dams, weirs, spillways, catch basins, baffle boxes, culvert
pipes, inlets, outlets, and outfalls. These assets have a virtually zero tolerance for
pests, as they must stay clear of vegetation and debris at all times in order to
function.
➢ Canals: shoreline and seawall vegetation is acceptable and often encouraged.
However, vegetation must be controlled to the seawall perimeters so that the
storage and flow of the waterways is maintained.
➢ Ponds: shoreline emergent vegetation is encouraged. However, when the
vegetation is not maintained, it can quickly take over these assets, reducing
stormwater storage capacity and degrading habitat quality.
➢ Ditches: and right-of-way (ROW) areas have the highest tolerance threshold for
pests, maintenance required is minimal.
• Erosion and runoff potential of site
• Proximity to other surface, surficial, and groundwater resources

Other Factors. Additional factors relevant to the selection
• Special equipment or storage required for method
• Method of delivery
• Chemical application must adhere to the standards of the City's Fertilizer Ordinance
Ch.50 Sec.50-5 (Appendix C)
• How all criteria may be affected by weather conditions
• Previous pesticide applications on site and interval between treatments
• Chemical application set -backs from slopes along waterways
• Possibility of pest resistance
• Equipment cleaning consideration before and after use
• Potential synergistic effects of pesticide combinations
The following considerations are addressed through the use of the Environmental Impact
Quotient (EIQ), which is explained on page 21:
Health and Safety Concerns. Potential effects on City staff and residents.
• Toxicological properties and potential health effects of materials or methods
• Equipment operation safety issues
• Staff safety and injury concerns
Environmental Considerations. Protection of native plants, animals and pollinators.
• Consider toxicity or potential harm caused by the method to non -target organisms and
habitat.
• Potential for bioaccumulation of materials within soils and groundwater
• Know if there is potential for negative effects from any pest control method or lack
thereof on any federally or state protected species that may be in the area
• Be aware of any nesting birds in the area and potential affects the method may cause
• Understand the effects the method may have on pollinators
• The effects of reduced control of invasive plants or pests to native biodiversity
Product Characteristics. Specific product features
• Possible residual effect and decomposition products
• Volatility and flammability
• Product formulation, recommended dilution and package size
• Leachability and solubility
